Summary:Now a days the power system structure is growing continuously. So the reliability has become a big task for the protection engineers. This paper presents a fast and accurate fault detection technique which is very much useful for reliable operation of the power systems. To achieve fastness and reliable operation various new technologies have been used but out of all the available equipment the use of phasor measurement unit have brought the reliability index to a significant level. An intelligent approach for fault detection has been used in this paper which adapts for changes in the operation level. It uses synchronized samples of the operation voltages and currents from both the ends of the transmission line to detect, and classify the fault. This technique has been implemented on IEEE 57 bus system and it was found that this method has given better results than the methods proposed earlier. With the use of modern equipment which limits the time of operation for few cycles, the time window can be reduced significantly.
